After autopatcher patched BIOS flash the motherboard is playing a nice melody tune and does not turn the display on. Found the error code via lenovo diagnostics app. I have taped the tamper switch.

Model: THINKPAD-P52-TYPE-20M9-20MA
Error code: 0285
Description: TGC-compliant functionality-related error (might be TPM initialization error)

Can I change some "Security Chip" variable in NVRAM to false so it would not go to TPM at all?
Any recommendations? I read and checksummed the bios after write just in case, it matched with what was sent....
